Something is definitely corrupt, as that value should be [1], not [[1]]. If it’s happening with every single series then you have a couple options:

  • Remove and re-add all series
  • Fix the issue via SQL editor, something like UPDATE EpisodeFiles SET Languages = '[1]' would reset the language for every file to just English.

THANK YOU!! that fixed my issue and saved me a few hours of removing and re-adding shows. ran the command in sql editor took a few seconds and all my series were fixed. Used SQLiteStudio opened database located in C:\ProgramData\Sonarr\sonarr.db entered in the command markus101 offered (UPDATE EpisodeFiles SET Languages = ‘[1]’) and clicked the run button. Took a few seconds and everything’s fixed.

If you have the same issue, that’s the only fix.

Thanks so much! That simple SQL edit also fixed the “unable to load episode files” issue for me.

Pro tip for anyone else who might be dumb or brand new to SQL editors: all you have to do is execute the command (UPDATE EpisodeFiles SET Languages = ‘[1]’), verify that things were modified and that there weren’t any errors in the status log, and then disconnect from the database. Took me longer than I’d like to admit to realize that you don’t have to save or export a ‘fixed’ DB - it’s already been modified as soon as the command is executed.
